A device adapted to be circumferentially fitted around the forearm to alleviate symptoms of overuse injuries, such as tennis elbow. The device is an elongate band composed of two elongate arcuate compression plates detachably and adjustably linked end to end by flexible straps. Each of the compression plates has an inwardly concave skin contacting surface which, in operation, are in circumferent opposition on the forearm to compress the skin overlying the radial extensor and flexor muscles within the forearm transaxially disposed therebetween. When the band is circumferentially tensioned and fastened to encircle the forearm, only the discrete, anatomically opposed skin contacting surfaces of the compression plates press against the skin. The skin contacting surfaces of the two compression plates are positioned by the user to immediately overlie the extensor and flexor muscle mass respectively. Only the skin underlying the skin-contacting surface of the compression plates and the intervening tissue transaxially disposed therebetween is compressed. Other circumferential portions of the forearm underlying the band are not compressed and the venous blood return is substantially unimpaired by the band.
